The door of the main control room of the war fortress opened, and a robot came in with a meteorite fragment and came to Ye Zan and Lin''s sister and brother. Ye Zan went forward, reached out his hand to pick up the meteorite fragment, turned his hand to linlimu and said, "look, this is what was cut from the meteorite. The whole meteorite is this kind of thing."


    Lin Limu was very excited, but when he took the meteorite fragment, he suddenly looked a little disappointed and said, "ah, what, it''s a piece of red fine copper. I thought it was a treasure!"


    This red refined copper is a kind of refined copper with fire property. It can be regarded as a good refining material in the domain boundary. More importantly, it has huge reserves in the domain and is an entry-level refining material with high quality and low price. It can be said that even if the whole body of this meteorite captured by the war fortress is red fine copper, I''m afraid it can''t be replaced with a top-grade spirit stone.


    If someone else had such a large piece of hematite in the domain, it would be a considerable wealth. However, for ye Zan, they really don''t get much from running into the endless void to get such a meteorite. If ye Zan returns now, the value of this red refined copper meteorite is not enough for the "oil money" up and down.


    In the face of such a harvest, the trees and trees who want to find treasure in the endless void will naturally feel quite disappointed. In fact, not to mention a red fine copper meteorite, even a Lingshi mine of the same size is not a harvest in the eyes of Lin Limu.


    "What else do you want? It''s an endless void. Everything you encounter depends on luck. You think you''re in your own home!" Lin Miaomiao said to his brother unhappily.


    In the endless void, after all, there are no more minerals underground than on the land of the domain boundary. Basically, when you encounter something, you get something. There is almost no choice. If the flying is a red fine copper meteorite, you can only get red fine copper. If the flying is a spirit stone meteorite, you can naturally make a small windfall.


    Although yezan has a fortress of war and can fly and move in the endless void, luck is still very important. Perhaps, when you are unlucky, you can fly in the endless void for a long time and encounter nothing valuable. If you are lucky, you may stop here without moving, and all kinds of treasures fly over to "throw themselves into the net".


    Ye Zan is also quite helpless. Although there are some detection means, it is impossible to explore the whole endless void. Ye Zan took back the meteorite fragment from Lin Limu. While giving it to the robot to take away, ye Zan said, "yes, this endless void is called an endless treasure, but we also need good luck."


    "Don''t worry, brother Ye. With our luck, there will be better babies coming to the door!" Linmu changed a smiling face and said to Ye Zan again. The main reason why he was disappointed just now was that he discovered the meteorite first. What you find, tell others happily, but the result is worthless. Naturally, you can''t help being disappointed.


    "Ha ha, I''m not as impatient as you. We have plenty of time to look for better things." Ye Zan smiled back, stopped for a moment, and suddenly said, "moreover, the meteorite you found this time is not as simple as it looks."


    "What do you mean?" Lin Mu was stunned and asked rather puzzled.


    Ye Zan directly pointed to the display screen next to it, which immediately showed the scene of cutting the meteorite, and said, "the meteorite center has just been dug over there. What do you think is the center?"


    Lin Lin turned his eyes to the display screen, carefully stared at the picture above, and suddenly said excitedly, "brother ye, is that the red refined copper mother? If the copper mother, this time is really not in vain!"


    Although red refined copper is not a precious metal, the mother of red refined copper is different. Although it sounds like there is not much difference between the two, and they do have homology in essence. However, the essence of the red copper can be said to be the essence of pure copper, and a complete copper vein of Chai Jing is likely to produce a large fist of copper. Now, yezan and his team have dug out a piece of red fine copper mother with the size of a human head from this red fine copper meteorite.


    There is a saying that "rare things are precious". Of course, this is not an absolute truth for the world of monks. After all, some things, although rare, are of little use, and naturally their value cannot be much higher. However, apart from the rarity of the copper concentrate, the essence of the whole refined copper vein is far superior to ordinary copper.


    In today''s Shenhua domain, although the reserves of red refined copper are still large, most of the mother copper has been excavated long ago. Therefore, the rarity of red refined copper mother is much higher than before. Of course, if the value of such a piece of red refined copper is so rebellious, it won''t be. But relatively speaking, compared with all the red fine copper of this meteorite, the value of this red fine copper mother is nearly a thousand times higher.


    As I said before, relying on the red refined copper of this meteorite, if ye Zan returns directly, I''m afraid there''s not enough "oil money" for the war fortress. However, now with this red refined copper mother, not only the "oil money" of this trip has come back, but it is no problem to run more than a dozen times.


    A moment later, such a large red fine copper meteorite had been cut clean. The red fine copper mother was sent to the main control room by the robot, which made the trees happy. However, Lin Lin is just a pleasure. After reading it, he threw it back to Ye Zan and put it away. After all, the value of this red refined copper mother is high, but it also depends on who it is for. At least, in linlimu, such a piece of red refined copper mother is not really regarded as a treasure.


    In addition to the hematite concentrate copper mother, other hematite concentrate copper ores are directly sent to the factory area by robots, where they are smelted into pieces of hematite concentrate copper ingots. Ye Zan doesn''t intend to sell the red refined copper. Anyway, he doesn''t care about the money sold. He might as well use it as reserve materials for robots or fortresses.


    As for the red refined copper mother, ye Zan is going to throw it to yuqingzong and ask them to refine magic weapons for those in need.


    "Well, let''s go on."


    After cleaning up the meteorite, yezan again issued instructions to let the war fortress continue to fly along the "atmosphere" of the domain boundary. Maybe it''s because ye Zan didn''t go too far. He didn''t encounter too many valuable things all the way down. Although several meteorites were captured, there was no such thing as red refined copper mother among those meteorites. They were only metals of low value.


    Meanwhile, all the way down, yezan''s war fortress was attacked by several empty storms. With radiation protection, several void storms survived safely. Only the strongest void storm forced yezan to open the energy shield of the war fortress. But even if the energy shield is turned on, the situation of the war fortress is much better than that before the upgrade. It hardly consumes much energy and rushes out of the void storm.


    However, ye Zan is not very disappointed. After all, the main purpose of entering the endless void this time is to test the effect of radiation protection. Being able to harvest something, whether it''s a relatively low-value metal or a rare piece of red refined copper, is an unplanned harvest.


    "Almost, we can go back." Ye Zan said to the Lin family after several tests and obtaining enough data. After obtaining these data, he already had a plan to improve and upgrade radiation protection through the calculation of auxiliary chip, which can be implemented immediately after he goes back.


    "Ah, are you going back? But it seems that we haven''t found any treasure this time." when Lin Limu heard that he was about to return, he still seemed to have some unfinished business. After all, being able to enter the endless void is a very rare experience, or a capital worth boasting, for the vast majority of people.


    "It''s not that you don''t have a chance in the future! When everything is on track, I''m afraid you''ll be tired of this endless void." Ye Zan said with a smile.


    Ye Zan''s words are not exaggerated. After all, exploring in this endless void will be very boring most of the time. If you want scenery, there is no scenery, and if you want stimulation, there is no stimulation. Sometimes you may not be able to encounter valuable things for a long time. Under such circumstances, not to mention people with jumping temperament such as Lin and mu, even ordinary people who think they can stand loneliness will certainly be bored over a long period of time.


    Lin Lin didn''t think so far, so after listening to Ye Zan''s words, he immediately said, "ha ha, how can it be! In the future, even if I live in the endless void, I won''t be bored."


    "Well, I wish you could say that. I''ve recorded all your words. If you complain to me later, I''ll show you your words." Ye Zan joked.


    Hearing this, the forest tree was embarrassed and said helplessly, "brother ye, we don''t have to do this!"


    "I think brother Ye is a good idea. I also want to wait and see how you will react when you see the answer at this time." Lin Miaomiao smiled and said.


    After a few jokes, ye Zan gave the war fortress an order to return. However, this return is not a direct fall. After all, they have been far away from the Tongtian peak after this period of time. Therefore, yezan also needs to let the war fortress fly back over Tongtian peak, and then land from there.


    The war fortress turned and flew in the direction of coming. Although it had such a huge volume, the speed of flying was not slow at all. Just like the cosmic stars in the world of science and technology, there is no air resistance in this endless void, so the huge volume has little effect on the flight speed. On the contrary, after returning to the domain boundary, the speed of the war fortress will become much slower, which can''t compare with the flying speed of the flying shuttle.


    Before long, the war fortress was close to the sky peak, but the alarm of artificial intelligence suddenly sounded in the main control room.


    "Alarm, a UFO is approaching quickly!"


    Hearing the alarm, ye Zan and Lin''s siblings were surprised and quickly looked at the display screen in the main control room. On the display screen on the front of the main control room, the scene in the endless void is displayed, and there are signs of artificial intelligence on it. At a seemingly distant location, AI is marked with a red cursor, which looks like several eye-catching red dots are flying quickly.


    "Brother ye, what''s the situation? Is there any treasure to be delivered to the door?" Lin Limu said excitedly.


    However, ye Zan''s face was a little serious. He stared at the red dot on the display screen and said in a deep voice, "it''s not a meteorite. I''m afraid the other party is not good!"


    "What, what kind of creature is it?" the forest wood also frowned, stepped forward and looked carefully at several red dots in the display screen.


    At this time, ye Zan also gave instructions to AI to enlarge the red dot on the display screen. With Ye Zan''s instructions, the display screen immediately changed, a box appeared around the red dots, and then expanded to the whole display screen. In this way, several red dots in the box become larger and clearer on the display screen, showing the true face of each other.


    "Hiss, what kind of monster is this? It can''t be the legendary void creature!" when he saw the image in the display screen, the trees took a breath of air-conditioning.


    "Very likely!" yezan simply replied four words, and sent out instructions through the auxiliary chip, making the whole war fortress ready immediately.


    After all, ye Zan is also the first time to encounter a real legendary void creature in the endless void, so he can''t help feeling a little nervous. Previously, in the empty battlefield of the Arctic fairy palace, he had seen the monsters left by Xuanqing Daozu, which seemed to be empty creatures. But those monsters are not really empty creatures, and their strength has been suppressed.


    Now, ye Zan meets these empty creatures in the endless void, but no one deliberately suppresses their strength. Therefore, if ye Zan is unlucky, it is not impossible to encounter some empty creatures of Tongtian level or even earth fairy level.


    "I hope these guys don''t have any abnormal existence." yezan took a long breath, restored the enlarged image on the display screen, and called out the battle assistance system of the war fortress.


    At this time, although the enlarged image was restored to its original shape, in fact, the empty creatures were very close to the fortress. After ye Zan called out the combat assistance system, he immediately ordered the fortress to attack. Beams of light shot out of the fortress in an instant and swept away towards the empty creatures.
